Description

Technical Field

[0001] The present invention relates to the technical field of storage boxes, and in particular to a maintenance tool storage box and a tool arrival detection system thereof. Background Art

[0002] Aircraft maintenance is an important measure to ensure passenger safety. Aircraft maintenance is inseparable from various professional maintenance tools. Due to the complex structure of the aircraft, a wide variety of professional tools are used in each maintenance. This greatly increases the difficulty of managing maintenance tools. Moreover, after maintenance, it is easy for tools to be forgotten at the maintenance site, misplaced or lost. In more serious cases, tools are left inside the aircraft body, which may lead to serious aircraft safety accidents.

[0003] At present, the storage boxes of aircraft maintenance tools are usually just simple storage containers, lacking effective management and detection mechanisms for tools, and cannot assist in the management of the return of aircraft maintenance tools. However, some toolboxes use RFID technology to realize tool return detection. This type of technology is to attach RFID tags to the tools, and then set up a RFID tag reading and writing device in the toolbox, and use the reading and writing device to detect whether the tools have been returned to the toolbox. However, the defect of this type of technology is that RFID is a range detection technology, that is, within a certain range, a specific frequency radio frequency band is transmitted through the reading and writing device. After the RFID tag detects the radio frequency band, it will return a signal to the reading and writing device. After the reading and writing device detects it, it indicates that the RFID tag exists in the area. Through this technology, the RFID tag is attached to the tool, and then the reading and writing device is installed on the toolbox to complete the automatic identification function of the tool return. However, due to its range design, the tools placed randomly in the toolbox cannot be identified by this technology, and once the tag falls off the tool, the corresponding tool loses the automatic identification function.

DETAILED DESCRIPTION

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0033] Embodiment 1, as Figures 1 to 10As shown, this embodiment includes a box body 1, a splitting component 2, a light detection system, a RFID detection system and a control system. A plurality of the splitting components 2 are slidably arranged in the box body 1. The splitting component 2 includes a drawer panel 201 and a drawer slot 202. A tool placement cavity layer 6 is arranged in the drawer slot 202. A tool placement slot 7 for placing tools is provided on the tool placement cavity layer 6. A light detection hole 10 is provided at the bottom of each tool placement slot 7. Each light detection hole 10 is provided with an LED lamp bead 16. A top signal receiving board 8 is also fixedly arranged on the top of each drawer slot 202. A photosensitive sheet 17 corresponding to the position of the light detection hole 10 is fixedly arranged on each top signal receiving board 8. After the corresponding tool is placed in the tool placement slot 7, the light emitted by the bottom signal transmitting board 13 at the light detection hole 10 is blocked by the tool, so that the corresponding photosensitive sheet 17 on the top signal receiving board 8 will not receive the light signal, thereby indicating that the part at this location has been placed in the tool placement slot 7, thereby avoiding the phenomenon of random placement of parts in the splitting component 2.

[0034] The RFID detection system includes an anti-metal tag fixed on each tool and a RFID reading and writing device. An internal tag reader 9 is fixed on each of the top signal receiving boards 8 in the box body 1. The internal tag reader 9 is used to read the anti-metal tag information of each layer, so as to quickly detect the return of the tools in each split component 2. At the same time, the anti-metal tag on each tool can also complete the rapid search of the tool through the search device when the tool is found to be lost. The two-way cooperation of the light detection system and the RFID detection system realizes the rapid confirmation, standardized return and rapid search effect of the tool.

[0035] Advantageously, a plurality of universal wheels 5 are fixedly provided at the bottom of the box 1, and the plurality of universal wheels 5 facilitate movement of the box 1 during maintenance. A temporary parts storage slot 4 is fixedly provided at the top of the box 1, and the temporary parts storage slot 4 is used for temporarily storing tools taken out of the box 1 during maintenance, so as to facilitate quick access during maintenance. At the same time, a display device 3 is also provided on the top of the box 1, and the display device 3 is a display control panel. When using the maintenance tool storage box of this embodiment, when the light detection system and the RFID detection system find that a tool is missing, the display device 3 will display information such as the exact tool location, so as to facilitate the operator to quickly find the specified location and thus confirm whether the tool is missing.

[0036] Furthermore, an external tag reader / writer 11 is provided on the outside of the box body 1, and the external tag reader / writer 11 is used to detect the use and return of tools in the splitting component 2 when the splitting component 2 is pulled out.

[0037] In this embodiment, the plurality of LED lamp beads 16 in the same split component 2 are all fixed on the same bottom signal transmitting board 13. The surface of the bottom signal transmitting board 13 is provided with a control circuit, and the control circuit can be processed on the surface of the bottom signal transmitting board 13 by surface etching. A magnetic telescopic tube 14 and an electromagnetic coil tube 15 are also provided at each of the LED lamp beads 16. The LED lamp bead 16 is located in the magnetic telescopic tube 14, and the magnetic telescopic tube 14 is located in the electromagnetic coil tube 15. The bottom end of the electromagnetic coil tube 15 is fixed on the bottom signal transmitting board 13, and the bottom end of each electromagnetic coil tube 15 is electrically connected to the control circuit on the bottom signal transmitting board 13. Then, the magnetic telescopic tube 14 is slidably matched with the electromagnetic coil tube 15. The electromagnetic coil tube 15 is controlled by the control circuit to realize the extension and retraction of the magnetic telescopic tube 14 in the electromagnetic coil tube 15. After the tool in the tool placement slot 7 above the magnetic telescopic tube 14 is taken out, the electromagnetic coil tube 15 controls the magnetic telescopic tube 14 to pop out. After the magnetic telescopic tube 14 pops out, other tools can no longer be placed in the tool placement slot 7. When the tool in the tool placement slot 7 is returned, the external tag reader 11 will detect that the tool enters the return area, thereby controlling the magnetic telescopic tube 14 to retract quickly, and then the user places the tool in the tool placement slot 7 where the magnetic telescopic tube 14 is retracted.

[0038] It should be noted that the benefit of this effect is that after multiple similar tools in the same split component 2 are taken out, the magnetic telescopic tube 14 in the tool placement slot 7 of each taken out tool is extended. When returning the tool, the tools are placed back into the corresponding tool placement slot 7 in turn. The external tag reader 11 detects the tool information and quickly controls the magnetic telescopic tube 14 to retract. The user can quickly and accurately find the correct return position of the tool through the rapid retraction of the magnetic telescopic tube 14, thereby returning the tool. Moreover, for some devices that are similar in appearance but different in appearance, it is often found that tools are misplaced with each other, such as socket heads or screw heads of different models. When they are used again after being misplaced, it is necessary to frequently find tools of corresponding models. In this way, the correct return of the tools can be ensured, thereby avoiding the phenomenon of tools being placed randomly on the same layer, making the tool return and sorting operations more standardized.

[0039] Advantageously, two porous plate pads 12 are provided on both sides of the bottom signal emitting plate 13. The porous plate pads 12 and the bottom signal emitting plate 13 are stacked to help the bottom signal emitting plate 13 dissipate heat. Meanwhile, the bottom signal emitting plate 13 is made of insulating material, which can also prevent the bottom signal emitting plate 13 from contacting with the metal drawer slot 202 and causing a short circuit.

[0040] In this embodiment, in this embodiment, the electromagnetic coil tube 15 includes a coil tube layer 1501 and a guide groove tube layer 1502, the coil tube layer 1501 is fixedly matched with the guide groove tube layer 1502, the inner wall of the guide groove tube layer 1502 is provided with a guide groove 1503, a fixed cylinder 1401 is fixed on the magnetic telescopic tube 14, the fixed cylinder 1401 slides in the guide groove 1503, and a magnet 1402 is fixed at the bottom of the magnetic telescopic tube 14, reference Fig. 9 , the guide groove 1503 is provided with 4 state points: D1, D2, D3, and D4. When the magnetic telescopic tube 14 is retracted into the electromagnetic coil tube 15, the fixed cylinder 1401 on the magnetic telescopic tube 14 is located at D1, and the magnetic field provided by the coil tube layer 1501 controls the magnet 1402 to push the magnetic telescopic tube 14 upward. Under the guidance of the guide groove 1503, the fixed cylinder 1401 moves from D1 to D2. At this time, the magnetic field direction of the coil tube layer 1501 is changed, and the magnetic telescopic tube 14 will fall to D3. When the coil tube layer 1501 is powered off, if the D 4, the magnetic telescopic tube 14 cannot be pressed back into the electromagnetic coil tube 15. If the magnetic telescopic tube 14 needs to be retracted into the electromagnetic coil tube 15, the coil tube layer 1501 is energized for a period of time, the fixed cylinder 1401 is controlled to move upward to D4, and then the magnetic field direction of the coil tube layer 1501 is changed to control the fixed cylinder 1401 to fall from D4 to D1. This design can effectively prevent the magnetic telescopic tube 14 from automatically retracting into the electromagnetic coil tube 15 when the coil tube layer 1501 is powered off, and can also prevent the magnetic telescopic tube 14 from being forcibly pressed back into the electromagnetic coil tube 15 by the tool that is returned incorrectly.

[0041] It should be noted that the coil tube layer 1501 is a coil tube wound with enameled wire, and the direction of the magnetic poles in the coil tube layer 1501 can be controlled by controlling the positive and negative directions of the connected enameled wire.
